Balsam Apple, an annual vine of the gourd family, cultivated mainly for ornament. It has a slender, tendril-bearing stem and thin leaves one to four inches (2.5 to 10 cm) across, with very sharp lobes and teeth. The rather showy flowers are white or yellow, one inch or more across. The fruit is egg-shaped, narrowed at both ends, and up to three inches (7.5 cm) long. The balsam apple is native to the tropics of the Eastern Hemisphere, but also grows widely elsewhere. It is quickly grown from seeds.
The balsam apple is Momordica balsamina of the family Cucurbitaceae.
